A great puzzle game! I played this as part of a pack of 8 Itch.io games on my Twitch channel.
I think one thing a lot of puzzle games struggle with is teaching you the mechanics without explicitly saying it. This game does that beautifully, with certain mechanics like the explosive barrel or the red enemies.
I liked the progression, although I did find the difficulty spike between certain rooms. This might just be me though. Overall a great short little puzzle game.
